It's difficult - if not impossible - to color regrade a movie only with some stills as reference... and, looking at the last comparison, it seems to me that the BD is pinkier than DVD... are you sure there are no other versions that could be used as color reference? Maybe a rare VHS, or a workprint DVD... (^^,)
And, I didn't want to be bad, and never thought you wanted to be bad, too... it's only a discussion between persons about an interesting topic, isn't true?
